By using the technique of the attenuated total reflection, the complex second hyperpolarizability for the quadratic electro-optic effect of a linear conjugated polymer is determined at the wavelength of the absorption edge by employing the data measured from different guided wave resonance dips. The values and the signs of the real and imaginary parts of the second hyperpolarizability are simultaneously obtained without employing the Kramers-Kronig transformation.
